Twilights Elite

They really help. I used them at night if I have to be on my computer or phone, or want to watch a movie.

Excellent delivery, and the glasses are great and do the job.

It definitely works as it should. So it's a good solution for circadian rhythm management. Especially if you are working night shifts like I do. Glasses are really dark. So TrueDark is not a marketing slogan. But be careful if you are planning to work with monitors of any machinery. Glasses are changing colors significantly. For the same reason, wearing glasses when you drive a car it's a good idea. This mentioned in the instructions. Overall, I really satisfied with this product. Looks good, feels good and definitely works good.
